Revolving mark of a Century. A Centiversary is like an Anniversary, only instead of being annual, it's centurial, or every 100 years.
In January of 2013, CalNORML and N.I.C.Events are hosting the first and LAST Centiversary Party of all time to mark the 100th year of Cannabis Prohibition in California, and hopefully the end of the Hundred Year War on Marijuana!
